GlLDlNG-MACHINE FOR BOOTS.

SPECIFICATION forming part of Letters Patent No. 442,915, dated December16, 1890. 7 Application filed August 18, 1390. Serial No. 362,266. (Nomodel.) i

To aZZ whom, it may concern:

Be it known that I, GEORGE H. PUTNAM, of Hopkinton, in the county ofMiddlesex, State of Massachusetts, have invented certain new and usefulImprovements in Gilding-Machines for Boots, of which the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which Figure l is afrontelevation of my improved gildinganachine; Fig. 2, a side elevationof the same; Fig. 3, a plan view, partly in section; and Fig. 4, asectional elevation showing the chute mechanism.

Like letters and figures of reference indicate corresponding parts inthe different figures of the drawings.

My invention relates especially to a machine for stampingorimprintingthe gild ing onto the top of boot-legs; and it consists incertain novel featureshereinafterfull y set forth and claimed, theobject being to produce a simpler, cheaper, and more effective device ofthis character than is now in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the standard or frame of the machine,which is hollowand provided at its top with a cylindrical head I). Asteam-box B is pendent in the head, and is adjustable vertically bymeans of a screw cl and nuts f. A steam-supply pipe 9 opens into saidbox. A die 7L for imprinting the gilding is mounted on the bottom of thebox B. A bar 1' is fitted to slide vertically in the standard and bearson its upper end a U-shaped head 7:, the arm Z of which is adapted to beinserted ina boot-leg and be forced into engagement with the die h.

A shaftm is fixed nearthe foot of the body A and bears a loosedriving-pulley p, the hub of which is extended at q, forming one sectionof a clutch G. A geart is loose on said shaft and is provided with anelongated hub on which a clutch-lever '17 is pivoted, said lever formingthe companion section of the clutch C. A spring u: on the lever-pivot(see Fig. i) acts expansively to throw said lever into engagement withthe opposite section q. One edge of the clutch-lever o is beveledperipherally, as best shown in Fig. 3. Acoiled spring a is interposedbetween the pulley and gear-hubs to prevent them accidentally workinginto contact. A treadle is mounted on the base of the standard. Ahorizontal lever 16, parallel with the treadle lever, is pivoted at 17to the standard above the shaft m and connected with said treadle by apivoted rod 18. The lever 16 has a lug 20, adapted to engage theclutch-section (see Fig. 4) and hold it out of contact with thecompanion section q. A coiled spring 21 connects said lever with thestandard. Ashaft 22, journaled in lugs 23 on the standard, bears a gear24:, which meshes with the gear 25. A vertical lever 25 is pivotedwithin the standard. A horizontal rod 26 is pivoted to the upper end ofsaid lever and bears an eccentric 27 at its outer end, which works onthe shaft 22. A screw-threaded rod 30 is pivoted by one end on the pivotof the eccentric-lever, its upper end working vertically in a sleeve 31,pivoted to the lower end of the bar 1'. A pin on said screw-threaded rodworks in a vertical slot (see Fig. l) in said sleeve. A nut 33, providedwith arms 34., works on the threaded rod 30, and a coiled tension-springis interposed between said nut and the sleeve 31.

In the use of my improvement, steam, being admitted to the box B, heatsthe die h. The boot-leg to be gilded is adjusted on the arm lot the headk. The operator then depresses 'the treadle 15, freeing the clutchsection v from the lug 20 of the lever 16. Said section is at oncethrown into engagement with the section g on the pulley rotating thegear 15. The eccentric 27 is driven by its shaft 22, moving thetoggle-joint D, formed by the lovers 25 and 26 and rod 30, into theposition shown in Fig. 2, forcing the bar 1' upward and the boot-legintov contact with the die 7b. The treadle is at once released, and atthe termination of revolution of the gear t the beveled edge of theclutch-section o, engaging the lug 20 of the lever 16, disconnects theclutch and stops the gears. The gears are so timed that a completerevolution of the pulley causes a semi-revolution of the eccentric.lVhen the clutch is disconnected, as de scribed, the parts are thus leftwith the boot held firmly in contact with the die. It rcquiring theapplication of heat for a considerable time to complete the gildingprocess, the operator by this arrangement of parts is not obliged totend the machine while this contact is effected. 13y again depressingthe treadle the clutch engages as before and the eccentric moves anotherhalf-revolution, actuating the toggle D and lowering the head 7,? out ofcontact with the die, when the boot may be removed.

Having thus explained my invention, what I claim is 1. In agildiug-machine for boots, a standard and die mounted thereon, incombination with a plunger provided with an arm for the bootleg, atoggle-joint, and operating mechanism for actuating said plunger,substantially as set forth.

2. In a gilding-machiue for boots, a body provided with a die, incombination with a plunger mounted on a toggle-joint, a drivingshaftactuating an eccentric for moving said joint, a loose pulleyon saidshaft, and a treadleactuated mechanism for fixing said pulley,substantially as described.

3. In a gilding-machine for boots, the combination of a body providedwith a steamheated die, a spring-cushioned plunger adapted to be forcedinto contact with said die, an eccentric for actuating said plunger, anda treadle-actuated clutch mechanism for intermittently driving saideccentric, substantially as described.

4. In a gilding-machine, a body or standard, a driving-shaft providedwith a loose pulley mechanism for automatically fixing and releasingsaid pulley, a plunger adapted to receive the boot-leg, a crank drivenby said shaft for actuating said plunger, and a die mounted in said bodyin position to be engaged by said plunger, substantially as set forth.

5. In a gliding-machine l'or boots, the com- I bination of a bodyprovided with a die, a spring-cushioned plunger having a head forreceiving the boot-leg, a driving-shaft and loose pulley, an eccentricdriven by said shaft for actuating said plunger, and a spring-actuatedclutch mechanism adapted to fix said pulley and automatically release itat the termination ofa revolution thereof, substantially as described.

6. In a gliding-machine for boots, the body, driving-shaft, and loosepulley, in combination with a spring-cushioned toggled plunger, aneccentric for actuating said plunger, driven by a shaft geared to thedriving-shaft, a spring-actuated clutch for fixing said pulley, and atreadle mechanism for governing said clutch, all being arranged tooperate substantially as described.

7. In a gilding-machinc for boots, the body provided with the steam-die,in combination with the toggled plunger-bar 1', having the head It, theshaft 22, and eccentric 27 for actuating said plunger, the shaft m andloose pulley p, the clutch C, and treadle mechanism for governing saidclutch, substantially as described.

8. In a gilding-machine for boots, the shaft on, loose pulley p, andgear 1, in combination with the clutch 0, comprising the beveled section0 and companion section q, and the treadle mechanism for governing saidclutch, substantially as described.
